REGISTERING APPARATUS FOR STEAM-ENGINES.

Specification of Letters Patent No. 31,582, dated February 26, 1861.

To all 'whom it may concern:

Be it known that I, PETER L. VEIMER, of Lebanon, in the county ofLebanon and State of Pennsylvania, have invented a new and ImprovedEngine-Registe; and I do hereby declare thatthe following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a front view of the register partly in section. Fig. 2 is avertical section of the same, at right angles to Eig. 1.

Similar letters of reference indicate corresponding parts in bothfigures.

My improved register consists of a box containing a train of indicatingwheels, the first. of which is actuated by a pawl or dog Carried ormoved by a Ypiston or diaphragm, which is arranged in a cylinder orchamber provided at one sideof the box, and which is to be acted upon tooperate the said pawl or dog at every stroke of the engine in onedirection by steam admitted to the said cylinder or chamber from one endof the engine cylinder.

To enableothers to make and use my invention I will proceed to describeits construction and operation.

A is the box, containing the wheel-work, made of cast-iron or othermetal, of a form suitable for the purpose, having in front a dial a, andhaving at. one side an opening b, communicating with the cylindricalchamber B, which is cast with it.

C, D, and E, are three ratchet wheels of similar or nearlysimilar sizeeach, having one hundred teeth. C, is faston a horizontal spindle c,which runs through the box and carries an index c. D, is fitted to turnupon the said spindle c, and carries an index CZ. E is fitted to turnupon a tubular extension (Z, of the hub of D, and carries an index e.The spindle c, has a bearing in the back of the box, and the hub of thewheel E, is furnished with a journal to work in a bearing in a ixed barE, arranged within the box. The three indices C, D, E, point to threeconcentric graduated circles on the dial a, the graduation of the outerone of said circles representing units up to one hundred `(100), that ofthe middle one hundreds up to ten thousand (10,000) and that of theinner one tens of thousands up to one million (1,000,000). The tube e,ofthe wheel E, has secured to it a pinion ot` ten teeth, and this piniongears with a spur wheel G, of one hundred teeth, that is fitted torotate on a fixed stud g, secured in the bar F. This spur wheel has itsouter tace divided into ten equal parts, and is marked at its points ofdivision from l to 10, such numbers representing millions and beingexhibited through a slot Zi, in the lower part of the dial a.

The ratchet wheel C, carries a pin a', which once in each revolution ofthe said wheel comes into operation on a lever H, working on a fixedfulcrum j, and carrying a pawl 7c, which by the action of the pin 2',upon the said lever is caused to move the wheel D, a distance equal toone tooth. The said lever has secured to it a spring Z, which by itsaction against a fixed stop m, is made to draw it back against a fixedstop a, and so drawback the pawl ZL, over a tooth of the wheel D, afterthe pin z', has ceased to act upon the lever. The wheel D, carries a pinz", like 2', operating in a similar manner on a lever H', like H,carrying a pawl c, like Zr, operating upon the ratchet wheel E, saidlever being controlled by a spring Z, like Z, and resting against thefixed stop m, when not in operation. The springs Z, Z, control the pawlsas well as their levers. t, t2, 253, are spring stop pawls to preventthe ratchet wheels from turning too tar, or turning the wrong way.

The chamber B, is bored horizontally for the reception of a looselyfitting piston L, which carries a rod ZL, passing through the beforementioned hole b, into the box A, within which it has secured to it aspring pawl y), which acts upon the rst or unit ratchet wheel O. Aspring g, is applied within the box A, to act upon the rod Zz, to forcethe piston away from the box B, and draw back the pawl from the teeth ofthe wheel O. The outer end of the chamber is covered by an india-rubberdiaphragm J, whose margin is secured by a metal cap I, which screws onto the end ot' the chamber, and this cap is provided with a nozzle r, towhich there is to be connected the pipe from one end ot the enginecylinder.

Every time steam is admitted to that end of the engine cylinder withwhich the nozzle r, is connected the steam presses upon the flexiblediaphragm lI, and through it upon the piston L, and so forces the said lient application than those Which are actuated by some moving part ofthe engine, as it is only necessary to drill a hole in the cylinder andmake the connection by a piece of pipe of suitable length to adapt it toany engine, Whatever its form or size; While in those which are actuatedby a moving part of the engine some special arrangement of mechanism'isnecessary to adapt it to each particular forni or pattern or Size ofengine.

That I claim as my invention, and desire to secure by Letters Patent, is

An engine register composed of a box containing a system of Wheel-WorkWith dial and indices, having attached to it a cylinder or chamber B,Which contains a piston L, and diaphragm J, or their equivalent,carrying a pawl p, suitably applied to act upon the first Wheel of theseries Within the box; the Whole so combined, substantially as hereindescribed, that the connection of the chamber by a pipe With the enginecylinder is all that is required to set the register in operation.
